The 13-year-old from the Netflix series posted photos on Instagram showing her meditating in a garden, strolling around her hotel and taking pictures with the staff on the Indonesian tourist island.

She wrote: "Hi guys, I just wanted to let you know that I have been in Bali after traveling through Australia. I wasn't able to return home after a four day break turned into 10 days due to the volcano."

She offers prayers for the tens of thousands of Balinese who have been affected by the ash-spewing Mount Agung.

Bali airport reopened Wednesday after being closed for 2 1/2 days and thousands of tourists are now leaving the island.
